Turbidity is a measure of water clarity. The loss of
clarity is usually caused by mud, silt, organic material
and chemical precipitates suspended in the water column.
Turbidity has been measured in Oregon in nephelometric
turbidity units (NTU) since 1990. That method
essentially measures how deep into a water column we can
see with the naked eye. An average person can see an
object nearly three feet under water at a turbidity
level of 5 NTU. That also happens to be the normal
allowable standard for drinking water. In contrast,
relatively clear lakes often have turbidity of 25 NTU,
visibly muddy water may measure 100 NTU, and at 2,000
NTU water is virtually opaque.
Current standards (OAR 340-041-0036) set allowable
summer turbidity in Oregon water bodies at levels less
than or equal to the established 5 NTU drinking water
standard. The Oregon Department of Environmental Quality
has set about the minimum level for the protection of
aquatic life and their habitats. In many Oregon water
bodies this standard leaves little if any margin for
anthropogenic activities. In fact, the preponderance of
eastern and southern Oregon water bodies may have normal
background levels that already exceed that standard
during much of the summer and fall.
The ODEQ is currently in the process of adopting new
administrative rules regarding that allowable turbidity
in Oregon water bodies. I have deep concerns regarding
the Department’s process in creating the new rules,
their proposed level of enforcement, and the apparent
lack of consistency in exerting their current
enforcement power.
In my opinion the proposed composition of the committee
is heavily weighted toward representatives of government
agencies and environmental organizations. The committee
will not operate under consensus but will function under
majority rule. Those expressing minority positions will
have the opportunity to have their concerns noted.
Moreover, ODEQ staff will create the background legal
and environmental frameworks from which the committee
will work. They will suggest the content of draft rules,
and will edit any of the committee’s proposed changes in
the rule drafts. The staff will record committee
positions on flip charts and then develop brief
summaries of those positions for the committee and the
public. There is no mention of requirements to either
record the meetings or to keep accurate and
comprehensive minutes of the meetings.
The protocol makes clear that ODEQ may or may not accept
the committee recommendations. In my opinion, ODEQ staff
has a long history of systematically ignoring public
input that does not support their intended actions. The
too familiar structure of the committee protocol
suggests that will not change.
ODEQ staff will then recommend their draft rules that
are supposedly blessed in this manner by the public
committee, to the Environmental Quality Commission. The
final rules adopted by the EQC must then be approved by
the U. S. Environmental Protection Agency.
The Savage Rapids and Gold Ray dams on the Rogue River
were demolished without regard to the decades of
sedimentation that had accumulated behind the dams. That
sediment was summarily turned loose down the River for
the people and the aquatic species to deal with. Many
people who live on the Rogue River have stated that they
believe that the River below the dam sites is sick,
being smothered by that sediment plume moving down
river. I know of no government studies even attempting
to measure either the amount of the sediment behind
those relatively small dams or the damage that the
sediment may be causing.
The Draft Environmental Impact Statement recently issued
by the Department of Interior proposes the demolition of
the four hydropower dams on the Klamath River without
regard to an estimated 20 million cubic yards of
sediment accumulated behind those dams. They propose to
simply let nature take its course and wash the sediment
downriver. That amount of sediment is equivalent to
about 2 million ten yard dump truck loads of silt,
sediment and organic muck. To put that amount into
perspective, lined up head to tail, 2 million dump truck
loads of river muck would stretch about half way around
the planet. Another report previously commissioned by
the Department of Interior, the Camp, Dresser & McKee
report, suggests the 20 million cubic yard estimate may
be a gross underestimation of the actual amount of
sediment accumulated behind the dams.
It appears that our government regulations have two
standards.
One standard holds private citizens to a standard that
severely restricts, or virtually bars their activities
in or near water bodies. Removal and fill activities,
recreational mining, as well as forest road construction
and maintenance require obtaining expensive time
consuming permits. Often the permits are denied citing
too much potential sediment disturbance and release. We
are told that large fines are routinely levied for minor
infractions of the sediment and turbidity rules.
The other standard allows government entities to do
pretty much whatever they wish so long as their purpose
is politically correct and adheres to the desires of the
environmentalist agenda.
How can we justify dumping the equivalent of two million
dump truck loads of sediment into the Klamath River to
expedite the politically correct demolition of
hydroelectric dams, while at the same time citing and
prosecuting foresters, agriculturalists and
recreationalists for stirring up a little sediment in
their pursuit of family entertainment?
Please remember, if we do not stand up for rural Oregon…
no one will.
